IIVORATIO C. HAWKS, OF NEWTON, MASSACHUSETTS.

REFLECTO R.

SPECIFICATION forming part of Letters Patent No. 716,891, dated December30, 1902- Application iled October 17, 1901. Serial No. 78,951. (Nomodel.)

E'. @ZZ whom, it may con/cern,.-

Be it known that I, HoRATIo C. I-IAwKs, of Newton, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Refiectors, 'of which the following is aspecilication.

The invention relates to reiiectors for incandescent electric lamps.Heretofore this class of reectors have been provided with a flanged neckat the central opening, and it has been customary to employ anintermediate device for securing the reflector to the lamp-socket. Thisintermediate device has been provided with a clampingring for securingit to the lamp-socket and has been provided with three or more screwsextending radially inward from the rim of the device and arranged toengage the neck of the reiiector below its flange, and thus hold thereflector in place.

In the present invention the reflector is provided with a splitclamping-ring for embracing the lamp-socket, which ring is permanently.secured to the reflector` by arms so arranged that the ring issupported concentric with the central opening of the refiector and isfree to expand and contract in applying and securing the reflector tothe lampsocket. With this construction the reflector is simplilied andits manufacture cheapened, since no iianged neck is required. Theinstallation is also much simplified by eliminating the intermediateconnecting device, with a resulting reduction of cost to the consumer. Afurther advantage of this construction is that it enables the reflectorto be more conveniently applied to or removed from the lamp, and alsoacts to more effectively hold the reiiector in place, while presenting aless cumbersome and unsightly appearance.

In explaining the invention more in detail I will refer to theaccompanying drawings, in which- Y Figure l is an elevation showing areiiector embodying the invention. applied to a lampsocket, and Fig. V2is a detail plan view of the clamping-ring. Y

`the opening CL by means of arms b integral with the ring B and securedto the reflector- .body by solder or otherwise.

The ring B is divided or split at b' and is providedY withradiallyprojecting ears c, through'which the ends ofthe ring may bedrawn toward each other by a suitable bindingdevice-such, for instance,as the screw d. The arms b are so arranged that they will allow the ringB to expand in applying the reliector to a lamp-socketand to becontracted to draw the ring firmly around the socket.

In applying the reilector'to the socket S the screw d is loosened untilthe ring is free to expand sufficiently to pass over the end of vthesocket. The ring is then passed over the lower end of the socket, afterwhich the screw is tightened to draw the ends of the ring towardeachother until the ring rmly clasps the socket. Thus the reflector maybe quickly and convenientlyV attached I to or removed from thelamp-socket and when attached is effectively held in place by the clamping-ring which forms a part of the reiiector.

VVllat I claim, and desire to secure by Letters Patent, is-

A reector for electric lamps comprising a body portion having a centralopening for the passage of the lamp or lamp-socket, a splitclamping-ring for embracing the lampsocket having integral earsprojecting from its lower edgeand permanently secured to the body, and abinding device fondrawing the ends of the split ring toward each other,substantially as described.

In testimony whereof I have aiiixed my signature in presence of twowitnesses.
